Abstract
Capacitors comprising a dielectric at least partly covering the surface of an electrode material and forming an anode body are described. The anode body may be at least partly coated with a solid electrolyte comprising a conductive polymer. The capacitor comprises at least one polyglycerol, where the ratio of the amount of polyglycerol (M) to the amount of conductive polymer (M) in the capacitor is M/M>0.15, and the polyglycerol contains more than 50 wt. % of a mixture of tri- and tetraglycerol, based on the total weight of the polyglycerol. Processes for the production of a capacitor, an electronic circuit and use of a capacitor in a dispersion are also described.
